And, in OOB 16, with the PzB 39 (unit 114) accurately coming out in 9/39 (just 703 Panzerbüchse 38 produced in 1939), this leaves - in the words of George C Scott as the mad General in Dr Strangelove - an 'ATR Gap' in unit class 2- Inf-AT from 6/38 thru 8/39 inclusive.
Therefore, unit #417, the 13.2mm Mauser, needs a correction of end-date to 10/39 (overlap of 2 months to allow for PzB 38/39 replacement), as previously noted in 2011.
This avoids the German 'ATR Gap' har.

2. Plus, in OOB 21 - it is highly doubtful the-then scarce PzB 38/39 ATRs (wpn 88) would have been available to an overseas export client in 9/39 (units 33 & 500). Therefore, revise their start date to 8/40 or 9/40 (after fall of France) and check if any formations require adjustment.

FYI, I have now had time to check the modification of the start date for both units in OOB 21 to 8/40. This definitely does Not affect formation stability for either unit so should be ok.

(A) Also, I have to Correct a minor Error I made back in 2011 as to my thinking regarding the ammo loadout of the PzB M.SS.41 (40 AP / 10 Sabot) - wpn 137 - unit 603. For the following reasons the PzB M.SS.41 needs to be adjusted to 25 AP / 25 Sabot:
A) Unlike earlier PzB rifles it came out in 1941 when there was a more plentiful supply and is also available longest until end 1943;
B) It is an SS designed/issued wpn that naturally would have more priority for allotment of Sabot ammo;
C) Unlike larger calibre squeeze-bore weapons whose Sabot ammo was also produced using Tungsten, the 7.9mm calibre never experienced a Sabot shortage as ample was produced;
D) As an SS wpn its mode of employment would naturally have been shorter range engagements by well trained/motivated troops;
E) As with the 7.9mm EW 141 that was issued in 1942 (units 572, 573 & 858 - with 30 AP / 90 Sabot), the slightly more accurate PzB M.SS.41 (vs PzB 39) was designed for more shorter-range engagements using Sabot.
I believe my reasoning is sound on this issue.
Thoughts?
